What is Qi Zheng Si Yu?
In ancient Chinese metaphysics, Qi Zheng Si Yu (also known as Guolao Astrology) is one of the oldest astrological systems and the one closest to modern astronomy. Many stellar concepts later found in Zi Wei Dou Shu actually evolved from and were virtualized out of Qi Zheng Si Yu.
Unlike BaZi, which relies purely on Heavenly Stems and Earthly Branches, Qi Zheng Si Yu directly observes the real positions of celestial bodies in the sky at the moment of your birth. It combines the Sun, Moon, and the five visible planets with the Zodiac and China’s unique Twenty-Eight Lunar Mansions for interpretation.
Why is Qi Zheng Si Yu Charting Extremely Difficult?
Because it is true astronomical astrology. Producing an accurate Qi Zheng Si Yu natal chart requires massive and highly precise astronomical ephemeris data, along with precession (Ayanamsa) calculations. Historically, only the Imperial Astronomical Bureau possessed the capability to perform such computations. Our cloud engine integrates high-precision astronomical libraries to instantly reconstruct the real sky at your moment of birth.
What Do the Seven Luminaries and Four Extras Represent?
This system is composed of both physical planets and virtual orbital nodes:
Qi Zheng (The Seven Luminaries)
The Sun, Moon, and the five visible planets: Mercury, Venus, Mars, Jupiter, and Saturn. They represent the visible energies, personality traits, and manifested events in your life.
Si Yu (The Four Phantoms)
Rahu, Ketu, Purple Qi, and Yue Bei. These are virtual orbital points (for example, Yue Bei is similar to Black Moon Lilith in Western astrology, while Rahu and Ketu correspond to the lunar nodes). The Four Extras represent your subconscious, hidden karma, and unavoidable karmic entanglements.
